WLSINJL Mixed Bed DI Resin Filter Cartridge, 10''x 2.5'' DI Color Changing Replacement Cartridge, Deionized Resin for Spot-Free Car Wash System, Window Cleaning & Aquarium, 2-Pack

Why it's a great deal

• Mixed Bed DI Resin Removal TDS: mixed bed deionization resin efficiently removes total dissolved solids (TDS), calcium, magnesium, iron, and other hard water minerals. Delivers lab-grade ultrapure water that dries naturally without water spots, streaks, or residues – perfect for achieving a showroom-worthy shine on vehicles and crystal-clear glass.

• Color changing filter element is easy to know when to replace: Deionization resin has a color changing function, which will change from purple to orange after consumption, clearly indicating when the filter element needs to be replaced.

• Durable and efficient: Each filter can handle up to 1800-2000 TDS of water (depending on water quality) before changing color.

• Multi scenario and multi-functional: suitable for car washing (cars, motorcycles, RVs, boats), spot free washing; Window/glass cleaning (home, office), with no clear stripes; Aquarium water purification (removing harmful ions to protect fish and plants). A single filter can meet various household and hobby needs.

• 10 inch universal size easy to install: The standard 10 inch length is suitable for most filter housings (compatible with 10 inch DI filter systems). No tools needed - just unscrew the old ink cartridge and replace it with this one. The dual packaging design ensures that you have backup preparation when replacing, saving you from frequent reordering.
